private ldb API
ldb_sqlite3 is already working with this model and ldb_tdb will do
as soon as tridge finishes the tdb transaction code.
currently the transactions are always implicit and wrap any single
ldb API call except searching, the transaction functions are
currently not made public on purpose.
Simo.
avoid the horrors of posix locking, but it was preventing us having an
ldb open twice with different options. Now each ldb open of the same
file shares the same underlying tdb, but uses a different ldb
structure
- we do not support multpiple attribute components anymore, makes code a lot easier
they will be readded later if we found out they are really used, so far my tests
show w2k3 do not handle them as well
- fix escaping issues, move component value to be in an ldb_val structure
still need to handle binary values case
- make cononicalize functions leak less memory by giving a specific memory context
- fix tests scripts so that test-ldap can start
- make test not delete databases on completion so that I can inspect them
- moved the knowledge of attribute types out of ldb_tdb and into the
generic ldb code. This allows the ldb_match() message match logic
to be generic, so it can be used by other backend
- added the generic ability to load attribute handlers, for
canonicalisation, compare, ldif read and ldif write. In the future
this will be used by the schema module to allow us to correctly
obey the attributetype schema elements
- added attribute handlers for some of the core ldap attribute types,
Integer, DirectoryString, DN, ObjectClass etc
- added automatic registration of attribute handlers for well-known
attribute names 'cn', 'dc', 'dn', 'ou' and 'objectClass'
- converted the objectSid special handlers for Samba to the new system
- added more correct handling of indexing in tdb backend based on the
attribute canonicalisation function
- added generic support for subclasses, moving it out of the tdb
backend. This will be used in future by the schema module
- fixed several bugs in the dn_explode code. It still needs more
work, but doesn't corrupt ldb dbs any more.
cmdline credentials code (which will be done soon)
- added a ldb_init() call, and changed ldb_connect() to take a ldb
context. This allows for much better error handling in
ldb_connect(), and also made the popt conversion easier
- fixed up all the existing backends with the new syntax
- improved error handling in *_connect()
- fixed a crash bug in the new case_fold_required() code
- ensured that ltdb_rename() and all ltdb_search() paths get the read lock
- added a ldb_oom() macro to make it easier to report out of memory
situations in ldb code
instead of a search expression. This allows our ldap server to pass
its ASN.1 parsed search expressions straight to ldb, instead of going
via strings.
- updated all the ldb modules code to handle the new interface
- got rid of the separate ldb_parse.h now that the ldb_parse
structures are exposed externally
- moved to C99 structure initialisation in ldb
- switched ldap server to using ldb_search_bytree()
called from multiple backends. (ldb_sqlite3 needs it too.) Added parameter
for a callback function that determines whether an attribute needs case
folding.
- begin to prepare for sqlite3 in build process
- work-in-progress updates, on ldb_sqlite3
this object properties are now used as multivalue attributes
now all values inserted are checked against a "valid values table"
eg:
this form is now accepted:
dn: @ATTRIBUTES
uid: CASE_INSENSITIVE
uid: WILDCARD
this form is now rejected:
dn: @ATTRIBUTES
uid: CASE_INSENSITIVE WILDCARD
please update your .ldb files if you make use of @ATTRIBUTES
(sam.ldb heavily uses it)
the code passes all make test tests for both tdb and ldap, it also
passes the new test to check for wrong @ATTRIBUTES attribute values
Simo.
changes:
- ldb_wrap disappears from code and become a private structure of db_wrap.c
thanks to our move to talloc in ldb code, we do not need to expose it anymore
- removal of ldb_close() function form the code
thanks to our move to talloc in ldb code, we do not need it anymore
use talloc_free() to close and free an ldb database
- some minor updates to ldb modules code to cope with the change and fix some
bugs I found out during the process
the case sensitive/insensitive flags on sections of a dn. So if a dn
is made up of 4 attributes, and 2 of those are case insensitive and 2
are case sensitive, then all the attribute names are uppercases, but
only the values of the case insensitive attributes are uppercased when
forming the tdb key.
- added code to canonicalise the dn, removing leading and trailing
spaces from attribute names and values
- when the @ATTRIBUTES record changes, fix the dn keys of any records that should now have new
dn keys due to changes in the case sensitivity of the record
I really did this to allow me to make the WINS database properly case
insensitive, but it is also the correct general fix for ldb, as it
matches the LDAP specification (and w2k LDAP server behaviour)
this helps standalone building of ldb
renew the schema module
split code into functions to improve readability and code reuse
add and modify works correctly but we need a proper testsuite
Simo
- add tests for ldbrename
- disable all tests which regenerate the index
(this is broken for me...the process hangs,
tridge we need to discuss that)
- link only the needed stuff to the ldb tools
- build ldbtest inside samba
metze
- fixed a problem with searching for values containing an '=' sign
- fixed the semantics of attempting an attribute deletion on an attribute that doesn't exist.
- added some more ldb_msg_*() utilities
allocator. The way to use this is to call ldb_set_alloc() with a
function pointer to whatever memory allocator you like. It includes a
context pointer to allow for pool based allocators.
- added the ability to mark record attributes as being CASE_INSENSITIVE, WILDCARD or INTEGER.
- added the ability to support objectclass subclasses, and to search by a parent class
- added internal support for case insensitive versus case sensitive
indexing (not UTF8 compliant yet)
- cleaned up a number of const warnings
- added a number of helper functions for fetching integers, strings and doubles
- added a in-memory cache for important database properties, supported by a
database sequence number
- changed some variable names to avoid conflicts with C++
added ldbedit, a _really_ useful command
added ldbadd, ldbdel, ldbsearch and ldbmodify to build
solved lots of timezone issues, we now pass the torture tests with
client and server in different zones
fixed several build issues
I know this breaks the no-LDAP build. Wait till I arrive in San Jose for that
fix.
caused by someone recently ...
1. Add configure check HAVE_COMPARISON_FN_T to see if this is defined. I
have not checked this on Linux yet, but will do so soon.
2. Add the definitions of malloc_p, realloc_p etc.
3. Check for LDAP and don't build stuff that depends on LDAP if we don't\
have it.
It currently builds on FreeBSD but there is one warning printed out at the end.
people. Note that I decided to make it LGPL.
ldb is not finished yet, but enough of it is there for people to get
an idea of what it does, and quite a few simple tests work
